چکیده انگلیسی
Magnesium-based materials have promising mechanical properties and potential to serve as implants for loadbearing temporary applications. The main concern about such implants is their strength and resistance for the acting forces. In this investigation, magnesium-based biodegradable Mg65Zn30Ca4Gd1 alloy prepared by combination of innovative Mechanical Alloying (MA) and Spark Plasma Sintering (SPS) methods, was studied for the structure and mechanical properties. Structural studies were performed using X-Ray Diffractometer (XRD) and Scanning Electron Microscope (SEM). XRD studies were conducted to gain an overview of the phase composition in powdered and sintered samples. The energy dispersive spectroscopy (EDS) additionally determine the chemical composition of the samples. SEM observations were used to examine the morphology of the sinters on the fractured surface after the compressive tests. Mechanical properties of the Mg65Zn30Ca4Gd1 alloy were examined by compressive tests, to determine the compressive strength and Young's modulus of the samples at room temperature. The paper provides information about the density and porosity of the Mg-based alloy and additionally its corrosion resistance. Moreover the work shows advantages and possibilities of forming multi-compound, morphologically homogeneous alloys with high mechanical properties in the powder metallurgy processes.
